wheel VOLKSWAGEN GOLF GTI 2015 5G / 7.G Service Manual

WARNING
Failure to heed warning lights and instrument cluster text messages can cause the vehicle to break down in traffic and result in a collision and serious personal injury.
x Never ignore warning lights or text WARNINGS.
x Always stop the vehicle as soon as it is safe to do so.
WARNING
Driving with bad brakes can cause a collision and serious personal injury.
x If the brake warning light "2!+% or H does not go out, or lights up when driving, either the brake fluid level in the reservoir is too low or there is a fault in the brake system. Stop the
vehicle as soon as you can do so safely and get expert assistance ⇒ Brake fluid.
x If the brake warning light "2!+% or H lights up at the same time as the ABS warning light !"3 or J, the ABS may not be working properly. This could cause the rear wheels to lock up relatively quickly during braking. Rear wheel brake lock-up can cause loss of vehicle control.
x If you believe the vehicle is safe to drive, drive slowly and very carefully to the nearest authorized Volkswagen dealer, authorized Volkswagen Service Facility, or other qualified workshop and have the brake system inspected. Avoid sudden hard braking and steering.
x If the ABS indicator light !"3 or J does not go out, or if it lights up while driving, the ABS system is not working properly. The vehicle can then be stopped only with the standard brakes (without ABS). You will not have the protection ABS provides. Contact your authorized Volkswagen dealer or an authorized Volkswagen Service Facility as soon as possible.
x If the brake pads are worn or you notice changes in the way the vehicle brakes, immediately contact an authorized Volkswagen dealer or authorized Volkswagen Service Facility to have the brake pads checked and, if necessary, replaced.
NOTICE
Failure to heed warning lights or text WARNINGS can result in vehicle damage.
Parking brake

Fig. 131 Between the front seats: Parking brake.

Setting the parking brake
x Pull the parking brake lever up firmly.
x When the ignition is on, the indicator light G or 0!2+ appears in the instrument cluster display to
show that the parking brake is engaged ⇒ Warning and indicator lights.
Releasing the parking brake
x Pull the lever up slightly and press the release button ⇒ fig. 131 (arrow).
x While holding the release button down, move the lever all the way down.
WARNING
Improper use of the parking brake can cause accidents and severe injuries.
x Never use the parking brake to slow down the vehicle when it is moving, except in an emergency. Braking distance is much longer, since only the rear wheels are braked. Alwa ys use the foot brake.
x Never drive with the parking brake partially engaged. This can cause the brake to overheat and negatively affect the brake system. It will also cause the rear brake pads to wear prematurely.
x Never activate the throttle manually from the engine compartment when the engine is running and the automatic transmission is in gear. The vehicle will start to move even if the parking brake is engaged.
NOTICE
Even though the transmission is in Park (P), the vehicle may move a couple of inches (a few centimeters) forwards or backwards if you take your foot off the brake pedal after stopping the vehicle without first firmly setting the parking brake.
A warning signal sounds if you drive faster than about 4 mph (6 km/h) with the parking brake engaged.
Parking

x Make sure all passengers and especially children leave the vehicle.
x Take all vehicle keys with you when leaving your vehicle.
x Lock the vehicle.
On hills
Before stopping the engine, turn the steering wheel so that, if the vehicle starts to roll, its front wheels will roll into the curb:
x Facing downhill, turn the front wheels so that they point toward the curb.
x Facing uphill, turn the front wheels so that they point away from the curb.
WARNING
The vehicle exhaust system and the catalytic converter get very hot. They can cause fires and serious personal injury.
x Never park where the hot exhaust system could ignite flammable materials, such as brush, leaves, dry grass, spilled fuel, etc.
WARNING
Leaving the vehicle when the selector lever is not in Park (P) (automatic transmissions) can cause the vehicle to roll away. This can cause accidents and serious personal injuries.
x When leaving the vehicle, always move the selector lever to Park (P), engage the parking brake, and pay attention to the warning messages on the instrument cluster display at all times.
NOTICE
x Always be careful when you park in areas with parking barriers or high curbs. These vary in height and could damage your bumper and related parts if the front of your vehicle hits a barrier or curb that is too high while you are getting into or out of a parking spot. To help prevent damage, stop before the tires of your vehicle touch a parking barrier or curb.
x Always be careful when you enter a driveway or drive up or down steep ramps or over curbs or other obstacles. Parts of the vehicle close to the ground may be damaged (such as bumper covers, spoilers, and parts of the engine, suspension, and exhaust systems).
About the brakes

WARNING
Overheated brakes will reduce the vehicle's stopping power and increase stopping distances considerably.
x When driving downhill, the brakes have to work especially hard and heat up quickly.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could overheat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
x A damaged front bumper or a non-standard spoiler can reduce airflow to the brakes and make them overheat.
WARNING
Wet brakes or brakes coated with ice or road salt react slower and need longer stopping distances.
x Carefully apply the brakes to test them.
x Always dry brakes and clean off ice and salt coatings with a few cautious brake applications when visibility, weather, road and traffic conditions permit.
WARNING
Driving when the brake booster is not working increases stopping distances and can cause accidents and serious personal injuries.
x Never let the vehicle coast when the engine is switched off.
x If the brake booster is not working (such as when the vehicle is being towed), a lot more pedal force is needed to slow down and stop.
NOTICE
x Never “ride” the brakes by keeping your foot on the brake pedal when you do not want to brake. Constant pressure on the brake pedal can make the brakes overheat. Riding the brakes will substantially reduce braking performance, increase stopping distance, and can cause complete brake system failure.
x Before driving downhill, especially on hills that are long or steep, always reduce speed and shift into lower gear (manual or automatic transmission). This will let the vehicle use engine braking and reduce the load on the brakes. Otherwise, the brake system could overheat and possibly fail. Only use the brakes when you need them to slow the vehicle down more or to stop.
When the front brakes are serviced, you should have the rear brake pads inspected at the same time. The wear of all brake pads should be visually checked regularly. The best way to check for brake pad wear is to have your authorized Volkswagen dealer or authorized Volkswagen Service Facility visually inspect the pads through the openings in the wheel rims or from underneath the vehicle. If necessary, the wheels can be taken off for a more thorough inspection.

x Push the brake pedal down hard and hold it there. Don't take your foot off the pedal or reduce the force on the pedal!
x Do not “pump” the brake pedal or let up on it!
x Steer the vehicle while pushing down hard on the brake pedal.
x ABS stops working if you release or let up on the brake.
When ABS is doing its job, you will notice a slight vibration through the brake pedal and hear a noise. ABS cannot shorten the stopping distance under all conditions. The stopping distance may even be longer, for instance, when driving on gravel or on newly fallen snow covering an icy or slippery surface.
Brake Assist (BAS)
The Brake Assist System can help to reduce stopping distances. If you press the brake pedal very quickly, BAS detects an emergency situation. It then very quickly builds up full brake system pressure, maximizing braking power and reducing the stopping distance. This way, ABS can be activated more quickly and efficiently.
Do not reduce pressure on the brake pedal! BAS switches off automatically as soon as you release or let up on the brake.
Anti-Slip Regulation (ASR)
ASR reduces engine power directed to spinning wheels and adjusts power to the road conditions. Even under poor road conditions, ASR can make it easier to get moving, accelerate, and climb hills.
ASR can be switched on or off manually ⇒ Switching Anti-Slip Regulation (ASR) on and off.
Electronic Differential Lock (EDL and XDL)
EDL is applied during regular straight-line acceleration. EDL gently brakes a drive wheel that has lost traction (spinning) and redirects the drive force to other drive wheels. In extreme cases, EDL automatically switches off to keep the brake from overheating. As soon as the brake has cooled down, EDL automatically switches on again.
XDL is an extension of the Electronic Differential Lock system. XDL does not react to drive wheel slippage when driving straight ahead. Instead, XDL detects slippage of the inside front wheel during fast cornering. XDL applies enough brake pressure to this wheel in order to stop the slippage. This improves traction, which helps the vehicle stay on track.
WARNING
Driving fast on icy, slippery, or wet roads can lead to a loss of control and result in serious personal injury for you and your passengers.
x Always adjust your speed and driving style to road, traffic, weather, and visibility conditions. Never let the additional safety that ESC, ABS, BAS, ASR, and EDL can provide tempt you into taking extra risks.
x Braking assistance systems cannot overcome the laws of physics and always prevent loss of vehicle control. Slippery and wet roads are still dangerous even with ESC and the other systems!
x Driving too fast on wet roads can cause the wheels to lose contact with the road and “hydroplane.” A vehicle that has lost road contact cannot be braked, steered, or controlled.
x These systems cannot reduce the risk of accident, for example if you drive too fast for conditions or if you do not keep your distance from the vehicle in front of you.
x Although these systems are very effective and can help you control the vehicle in many difficult situations, always remember that your vehicle handling control is limited by tire traction.
x When accelerating on a slippery surface, for example on ice and snow, depress the accelerator carefully. Even with these systems, the wheels may start to spin, leading to a loss of vehicle control.

WARNING
The effectiveness of ESC can be significantly reduced if other components and systems that affect vehicle dynamics, including but not limited to brakes, tires, and other systems mentioned above, are not properly maintained or functioning.
x Always remember that vehicle alterations or modifications can affect the functioning of the ABS, BAS, ASR, EDL, and ESC systems.
x Changing the vehicle suspension or using an unapproved tire/wheel combination can change the way the ABS, BAS, ASR, EDL, and ESC systems work and reduce their effectiveness.
x The effectiveness of ESC is also determined by the tires fitted ⇒ Tires and wheels.
All 4 wheels must be equipped with identical tires in order for ESC and ASR to work properly. Differences in the tread circumference of the tires can cause the system to reduce the engine power when it is not expected.
If ABS is not working, ESC, ASR, and EDL will also not work.
You may hear noises when these systems are active.

WARNING
Even if empty, portable fuel containers can leak and cause a fire and serious personal injuries, especially in a crash.
x For your safety, we strongly recommend that you do not travel with a portable fuel container in your vehicle.
x If, under exceptional circumstances, you must transport a portable fuel container, please observe the following:
– Never fill a portable fuel container while it is anywhere in or on the vehicle (for example, in the luggage compartment). Static electricity can build up while filling and can ignite fuel vapors, causing a fire.
– Always place a portable fuel container on the ground before filling. Never spill fuel inside the vehicle or luggage compartment. Fuel vapors are highly flammable.
– Always keep the filler nozzle completely inside the portable container before and during filling.
– If filling a portable container made of metal, the filler nozzle must always be in contact with the container. This will help prevent static electricity from discharging and causing a fire.
– Always observe local and state or provincial laws about the use, storage, and transportation of portable fuel containers.
– Make certain that the portable fuel container meets industry standards, such as ANSI/ASTM F852-86.
NOTICE
x Remove fuel spills from the vehicle immediately to help prevent damage to the paint, tires, and wheel housings.
x Refueling with gasoline when your vehicle has a diesel engine or refueling with diesel fuel when your vehicle has a gasoline engine can cause very serious and expensive engine and fuel system damage that is not covered by any Volkswagen Limited Warranty.
x If you put any amount of incorrect fuel in the fuel tank, do not start the engine under any circumstances. Immediately contact the nearest authorized Volkswagen dealer or authorized Volkswagen Service Facility for assistance. These fuels contain substances that can severely damage the fuel system and the engine if the engine is started.
Fuels can pollute the environment. Spilled fuel must be collected and disposed of properly, following all applicable environmental regulations.
There is no emergency release for the fuel filler flap. Contact an authorized Volkswagen dealer or an authorized Volkswagen Service Facility for assistance.

x Unscrew the fuel cap counterclockwise and remove. Use the slot on the fuel filler flap hinge
⇒ fig. 151 to hold the cap while refueling.
Refueling
The correct fuel grade for your vehicle ⇒ Fuel is listed on a sticker on the inside of the fuel filler flap (arrow).
x The fuel tank is full when the automatic filler nozzle pump switches off the first time ⇒ .
x Do not try to add fuel after the pump stops! Topping off the tank in this way may fill the expansion space that the tank needs and cause fuel to overflow, for example, if it gets warmer outside.
Closing the fuel filler cap
x Screw the fuel cap clockwise onto the fuel filler neck until you hear it click into place.
x Close the fuel filler flap until you hear it latch shut. The fuel filler flap must be flush with the vehicle body.
WARNING
Spilled fuel can cause fires, explosions, burns, and other severe injuries.
x Always stop refueling once the pump nozzle switches off so that the tank does not overflow.
NOTICE
